Effective Portfolio Construction and Rebalancing Strategies

Portfolio Construction Strategies

1. Strategic Asset Allocation

This method allocates assets according to long-term investment goals and risk tolerance. For example, it can be structured as 60% stocks, 30% bonds, and 10% cash.

2. Tactical Asset Allocation

This strategy adjusts asset allocation in the short term based on market conditions. For instance, increasing the proportion of stocks during economic booms and increasing bond allocation during recessions.

3. Dynamic Asset Allocation

This approach continuously adjusts asset allocation in response to market changes. It's a more aggressive approach than tactical asset allocation.

Importance of Rebalancing

Rebalancing is the process of readjusting a portfolio to its original target ratios. It's important for the following reasons:

Risk management
Profit realization
Maintaining investment discipline

Rebalancing Strategies

1. Calendar-based Rebalancing

Readjusts the portfolio at set intervals (e.g., quarterly, annually).

2. Threshold-based Rebalancing

Executes rebalancing when the weight of a specific asset deviates from a set range. For example, adjusting when it goes beyond ±5% of the target weight.

3. Combination Strategy

Can combine calendar-based and threshold-based strategies.

Impact of Industry Cycles and Interest Rate Changes

It's important to consider the impact of industry cycles and interest rate changes when constructing a portfolio.

Industry	Interest Rate Increase	Interest Rate Decrease
Finance	Positive	Negative
Real Estate	Negative	Positive
Utilities	Negative	Positive
Technology	Negative	Positive
Consumer Goods	Negative	Positive

Industry cycles are closely related to economic cycles but can vary based on each industry's characteristics. Let's look at the key features of major industry cycles.

Industry	Initial Stage	Growth Stage	Mature Stage	Decline Stage
Manufacturing	Increased production, expanded facility investment, increased employment	Maximum production capacity reached, inventory increase begins	Decreased production, inventory adjustment, reduced employment	Inventory depletion, new orders begin to increase
IT Industry	New technology development, initial investment increase	Market expansion, rapid sales increase	Intensified competition, price decline	Replacement by new technology, market contraction
Construction	Increased housing starts, expanded construction investment	Increase in large-scale projects, employment expansion	Decrease in new projects, increase in unsold inventory	Reduced construction investment, restructuring
Finance	Increased lending, improved profitability	Asset value increase, risk increase	Increase in non-performing loans, deteriorating profitability	Restructuring, seeking new growth drivers
Energy Industry	Increased demand, price rise, expanded investment	Supply excess begins, price stabilization	Decreased demand, price fall, reduced investment	Reduced production, restructuring, seeking new equilibrium

Adjusting your portfolio considering these impacts can lead to better performance.

Investment Strategy Explanation:

Set stock allocation at 60% to pursue long-term growth. Mix individual stocks and ETFs to secure both diversity and stability.
Secure stability with a 35% bond allocation, expecting it to buffer against stock market volatility.
Maintain 5% in cash and short-term bonds for liquidity and to enable quick response to market opportunities.
Participate in overall U.S. market growth through S&P 500 ETF and individual large-cap tech stocks.
Maintain balance by mixing growth and dividend ETFs.
Seek interest income and stability through various types of bond products.
Regularly (e.g., quarterly or semi-annually) check asset allocation ratios and rebalance if necessary.
Conduct annual portfolio reviews based on market conditions and changes in personal investment goals.

This portfolio seeks a balance between growth and stability, managing risk by diversifying across various asset classes and sectors. These ratios can be adjusted according to individual investor situations and goals, and regular reassessment is necessary based on changing market conditions.

Conclusion

Effective portfolio construction and rebalancing are essential for long-term investment success. It's important to choose and consistently implement appropriate strategies considering personal investment goals, risk tolerance, and market conditions. Regular rebalancing can help manage risk and optimize returns.
